What Is the Best Thing to Do for a Sprained Ankle?

Protect it early, start moving it soon, and commit to rehabilitation exercises afterward. That sequence matters more than any single intervention. The old advice to rest, ice, compress, and elevate has been partially replaced by a broader framework emphasizing early controlled movement and exercise-based recovery, and the research consistently shows that people who begin gentle activity within days do better than those who stay immobilized for weeks.

Protect It First, Then Start Moving

The updated approach to acute soft-tissue injuries like ankle sprains is sometimes summarized as PEACE and LOVE, which stands for Protection, Elevation, Avoid anti-inflammatory modalities, Compression, and Education in the first days, followed by Load, Optimism, Vascularization, and Exercise as recovery progresses. The idea is that a short window of protection gives damaged tissue a chance to begin healing, while early and gradually increasing activity prevents the stiffness, weakness, and poor coordination that come from prolonged immobilization.¹

How soon is “early”? A trial comparing early mobilization to cast immobilization in first-time lateral ankle sprains found that the early-movement group had less pain at three weeks and was far more likely to have returned to full work by day ten, with roughly half back on the job compared to only about one in eight in the immobilized group. After a year, both groups had similar rates of residual symptoms and re-sprains, so early mobilization did not come at a cost of worse long-term outcomes.²

In practical terms, “protection” during the first couple of days means avoiding activities that provoke sharp pain, using crutches if weight-bearing hurts too much, and perhaps wearing a brace or supportive wrap. It does not mean lying on the couch for a week. As pain allows, you should start putting weight through the ankle, walking short distances, and doing gentle range-of-motion exercises like tracing the alphabet with your toes.

When You Need an X-Ray

Most sprained ankles are not broken, but a fracture can feel similar enough that it is worth knowing the signs. Emergency departments widely use a screening tool called the Ottawa Ankle Rules to decide who needs an X-ray. The rules flag specific red flags: bone tenderness at certain spots on the ankle or midfoot, and inability to take four steps immediately after the injury and in the exam room. A systematic review and meta-analysis of the rules found that they catch fractures with very high sensitivity, around 99%, meaning they rarely miss a break.³ The tradeoff is low specificity, so many people flagged by the rules turn out not to have a fracture after all. But the point is to be safe rather than sorry.

A separate meta-analysis found broadly similar numbers, with pooled sensitivity around 91% across studies, though with considerable variation depending on the population studied.⁴ The takeaway for you: if you can walk four steps, and pressing on the bony bumps on either side of your ankle and the middle of your foot does not cause sharp tenderness, you can likely skip the emergency department and manage the sprain at home. If any of those criteria are positive, get imaging to rule out a fracture.

For ligament damage rather than bone, ultrasound has emerged as a practical alternative to MRI. A meta-analysis of ultrasound accuracy for lateral ankle ligament injuries found sensitivity of about 97% and specificity of about 93% for the most commonly torn ligament, which is the one running along the outside front of the ankle.⁵ Another study found that point-of-care ultrasound performed in an emergency setting was essentially as precise as MRI for detecting major ligament and tendon injuries.⁶ This means your doctor may not need to order an expensive MRI to get a clear picture of what is going on inside the joint.

Ice and Pain Medication

Ice is one of the first things most people reach for, and it does help with pain in the first few days. A randomized trial comparing two icing protocols for acute ankle sprains found that intermittent icing produced less pain during activity than a standard twenty-minute application, though the advantage faded within a week, with no lasting differences in swelling, function, or resting pain between groups.⁷ Intermittent icing, where you apply cold for ten minutes, remove it, and repeat, appears to be the better strategy if you are going to ice at all.

Anti-inflammatory painkillers like ibuprofen and naproxen are the other common go-to. Evidence suggests that both oral and topical versions reduce pain in the short term compared to doing nothing.⁸ That said, the benefits are modest. One double-blind trial comparing high-dose ibuprofen to a placebo in acute sprains found trends favoring the drug but no statistically significant differences between groups.⁹

There is also a growing conversation about whether suppressing inflammation too aggressively in the early hours might actually slow healing. Inflammation is part of the body’s repair process, and interfering with it could theoretically delay tissue remodeling. The PEACE and LOVE framework explicitly suggests avoiding anti-inflammatory modalities in the first phase. In practice, most clinicians still use short courses of anti-inflammatories when pain is significant, but the days of popping ibuprofen around the clock for a week are fading.

Braces, Tape, and Wraps

Some form of external support helps during recovery and is strongly supported for preventing re-injury. The question is what kind. A review of the evidence found consensus that external ankle supports reduce the risk of future sprains, but the data on whether taping or bracing is superior remains inconclusive. The numbers lean slightly toward bracing in terms of efficiency: to prevent one sprain, you need to brace about 18 previously injured ankles for a season, versus taping somewhere between 39 and 57.¹⁰

Comfort and practicality also matter. A randomized trial comparing taping to semi-rigid bracing found that functional outcomes were similar, but patients in the brace group reported significantly higher comfort and satisfaction. Skin complications were dramatically different, with about 15% in the brace group developing irritation compared to nearly 60% in the tape group.¹¹ Tape loosens as you sweat and move, needs to be reapplied, and irritates skin. A lace-up or semi-rigid brace can be adjusted, taken on and off, and worn for weeks without those problems.

One trial comparing soft bracing to taping over a year found similar re-injury rates between the two (about 17% with bracing versus 14% with taping, a statistically insignificant difference), though the brace group scored slightly worse on a manual laxity test of the ankle.¹² The overall picture: if you have sprained your ankle before, wearing a brace during sports is one of the simplest and most effective things you can do to prevent another sprain, and braces are generally easier to live with than tape.

Rehabilitation Exercises

This is where most people drop the ball. The ankle feels better after a few weeks, so they go back to their normal activities without rebuilding strength and balance. That decision is the single biggest contributor to chronic problems down the road. Failure to complete functional rehabilitation after an acute sprain is what leads to chronic ankle instability, a condition where the ankle keeps giving way.¹³

A systematic review comparing supervised rehabilitation to home exercise programs found that supervised rehab produced less pain, less subjective instability, and greater gains in ankle strength and joint position sense.¹⁴ Not everyone needs a physical therapist for every session, but having professional guidance for at least part of the process appears to help. A separate randomized trial found no significant difference in re-sprain rates or subjective recovery between supervised exercise and conventional treatment alone at one year.¹⁵ So the evidence is mixed on whether formal supervision is strictly necessary, but the exercises themselves are not optional.

Balance training on a wobble board or unstable surface is one of the most studied rehab interventions. A randomized trial found that wobble board training significantly improved balance, proprioception, and jump-landing mechanics in people with chronic ankle instability.¹⁶ A case series of athletes with chronic instability found that while not every person experienced equal symptom reduction, no new sprains occurred during the wobble-board program.¹⁷

Strengthening the peroneal muscles, the ones running along the outside of your lower leg, also matters. These muscles are your ankle’s first line of active defense against rolling inward. Research on tennis players found that combined strength and neuromuscular training of these muscles improved joint stability and fatigue resistance.¹⁸ Simple exercises like resisting a resistance band wrapped around your forefoot while pushing outward can target these muscles effectively at home.

High Ankle Sprains Are a Different Animal

Everything above applies mainly to lateral ankle sprains, where you roll the ankle inward and damage the ligaments on the outside. A high ankle sprain injures the ligaments connecting the two lower leg bones just above the ankle joint, and it behaves differently. These injuries require prolonged recovery compared to their lateral counterparts.¹⁹

Among professional athletes, high ankle sprains can mean missing significant playing time. A study of professional ice hockey players found a median of eight games missed, with some players sidelined for as many as 65 games. MRI revealed complete tears of the main syndesmotic ligament in over 60% of cases, and bone bruising in about 71%.²⁰ The severity varies considerably. A prospective study of grade II high ankle sprains found that stable injuries allowed return to sport at a mean of 45 days, while unstable injuries took 64 days. Instability was much more likely when a squeeze test was positive or when the deltoid ligament on the inner ankle was also damaged.²¹

If your pain is above the ankle joint, between the two leg bones, or if rotating your foot outward hurts more than rolling it inward, suspect a high ankle sprain and get evaluated. These injuries are more commonly misdiagnosed or undertreated than lateral sprains, and returning to activity too early risks significantly longer setbacks.

How a Sprain Changes the Way You Move

A sprained ankle does not just affect the ankle. Research using motion analysis has shown that even an acute first-time sprain alters the way the entire leg moves during walking. People with a fresh lateral sprain walk with increased knee flexion, more ankle inversion, and reduced push-off power compared to uninjured controls.²² These are compensatory strategies, and they can become habits if left uncorrected.

Six months after injury, people who developed chronic instability continued to show abnormal movement patterns at both the ankle and knee during walking.²³ Researchers studying people with chronic ankle instability have documented movement and motor control problems that cascade upward from the ankle through the knee and hip.²⁴ This is one reason rehabilitation cannot focus on the ankle alone. Exercises that challenge the whole leg, like single-leg squats, step-downs, and landing drills, address these compensations before they become entrenched.

Chronic Instability and What Predicts It

Somewhere between a quarter and a third of people who sprain an ankle go on to develop chronic ankle instability, where the joint repeatedly gives way during daily activities or sport. A prospective study tracking first-time sprain patients found two early warning signs: if you cannot complete jumping and landing tasks within two weeks of the injury, and if your balance and self-reported function are still poor at six months, you are more likely to end up with chronic instability.²⁵

At the tissue level, chronic instability involves more than just a loose ligament. Research has identified ongoing inflammatory and fibrotic processes where the body lays down stiff scar-like collagen, combined with dysfunction in the mechanoreceptors that tell your brain where your ankle is in space.²⁶ This combination of structural looseness and impaired sensation is why chronic instability is so hard to fix once it sets in, and why early rehabilitation that retrains proprioception is so valuable.

Fear of Re-Injury Slows Recovery

An underappreciated factor in ankle sprain recovery is psychology. Fear of re-injury, sometimes called kinesiophobia, directly impairs physical performance. People with chronic ankle instability who scored high on fear-of-movement scales relied more heavily on their eyes for balance and reached less distance on dynamic balance tests than people with the same level of ankle instability but lower fear.²⁷ In other words, the fear itself made their balance worse, independent of how damaged their ankle was.

A study examining the relationship between physical activity levels and ankle function after sprains found that people who stayed more active reported fewer functional limitations, while those with greater movement-related fear had more restrictions in everyday ankle and foot function.²⁸ This creates a vicious cycle: fear leads to avoidance, avoidance leads to deconditioning, deconditioning makes the ankle less stable, and instability feeds more fear. Breaking that cycle requires gradually challenging the ankle in progressively demanding tasks. If you find yourself avoiding activities not because of pain but because of anxiety about re-injury, that is a signal worth addressing with a physical therapist.

When Are You Ready to Return to Sport?

Pain going away is not the same as being ready. A systematic review looking for criteria-based return-to-sport protocols after lateral ankle sprains found that no studies had actually used a formal decision-making process, despite widespread agreement that one is needed.²⁹ That gap has started to close. An international consensus panel developed the PAASS framework, which organizes return-to-sport readiness around five domains: pain during and after sport, ankle range of motion and strength, the athlete’s own confidence and psychological readiness, sensorimotor control like balance and proprioception, and sport-specific functional performance including hopping, jumping, agility, and completing a full training session.³⁰

There is also the Ankle-GO score, a recently validated objective tool that sums performance on six tests for a maximum of 25 points. At two months after injury, patients scoring below 8 points were unlikely to return to their pre-injury level of sport.³¹ While these tools are designed for competitive athletes, the principle applies to weekend joggers and recreational players too: test your ankle with sport-like movements before trusting it in a game. Can you hop on it? Land from a jump without flinching? Change direction sharply? If any of those feel unstable or painful, you are not done rehabilitating.

When Surgery Comes Up

The vast majority of ankle sprains heal without surgery. Even severe sprains with significant ligament damage generally respond well to conservative treatment. But for a subset of patients, surgery becomes relevant. A long-term follow-up study compared surgical and nonoperative treatment in patients with severe lateral ankle ligament injuries. In the surgical group, about 17% experienced a re-sprain but none needed additional surgery; four developed chronic instability. In the nonoperative group, about 32% re-sprained and six progressed to chronic instability.³² These were patients with severe initial injuries, not typical mild-to-moderate sprains.

A systematic review of chronic ankle complaints noted that while several studies reported good outcomes from various surgical techniques for persistent instability, none included a nonsurgical control group for comparison, making it hard to say definitively that surgery outperforms continued rehabilitation.³³ Surgery is typically reserved for people who have completed a full rehabilitation program and still have recurrent giving-way episodes that interfere with their daily life or sport. It is a last resort, not a shortcut, and even after surgery you will still need to do the same balance and strengthening exercises you probably should have done the first time around.
